提出了一种客观的定量方法来决定何时停止听觉脑干反应（ABR）测试中的平均扫描。该决定基于 (1) 对不同刺激水平下正常听力个体 ABR 中 V 波幅度分布的了解，(2) 对平均值中残余背景噪声的计算估计，以及 (3) 使用诱发电位的定量统计检测器。给出了终止平均值的几个原因以及针对每个原因的特定协议。这些协议提供了一个通用但一致的框架来解决何时停止平均的问题，并且应该提高 ABR 测试的效率。此外，完全有可能实现程序和决策过程的自动化。 (C) 1996 年美国声学学会。
An objective quantitative approach to the decision of when to stop averaging sweeps in auditory brain-stem response (ABR) testing is presented. This decision is based on (1) the knowledge of the amplitude distributions of wave V in the ABRs of normal hearing individuals for varying stimulus levels, (2) calculated estimates of the residual background noise in the average, and (3) use of a quantitative statistical detector of an evoked potential. Several reasons for terminating an average are presented along with a specific protocol for each of the reasons. These protocols provide a general but consistent framework to address the issue of when to stop averaging and should improve the efficiency of ABR testing. Furthermore, it is quite possible to automate the procedure and the decision process. (C) 1996 Acoustical Society of America.
